Question about Garden
Your problem is simple to explain, but unfortunately expensive to repair. Inside the engine atached to the cam is a small device called an Automatic Compression Release or ACR. It mounts on to a pin and it has a spring. One or the other or both are broken. When you remove the plug, it turns over easy because there is no compression to hold it back. Once you put the plug back in, its the job of the ACR to raise the valve just enough to get the engine started then it closes to let the engine run. The engine will have to be removed and the case split to replace it. I hate giving bad news. George

Concerning your starter/pull cord problem, what has probably happened is that due to sitting idle for an extended period, the pinion gear had stuck in the down position on the clutch drive.
When you engaged it with power it spun as it was supposed to do but did not immediately spin up into the ring gear.
After you released the starter button and it began to slow down the gear spun up into the flywheel and jammed because it didn't have enough power to turn the engine.
A usually simple fix for this is to turn the engine backward by hand just enough to relieve the tension and the return spring will push the gear back down.
At this point, you can try the electric starter again and it should work properly. If it does not work, you will have to remove the starter and clean and inspect the starter drive on the top of the starter.
Concerning the fact that it would not start, you more than likely have some old fuel trapped in the bottom of the float bowl.
You may be able to remedy this by spraying some carburetor cleaner in the carb while trying to start it.
If it has spark and everything else is in good condition, it will start and run as long as it has carb cleaner getting to the engine so you may need to spray it a few times while it is running on that and sometimes the stale fuel problem will clear itself.
If it doesn't clear up and run on its own without the carb cleaner after 3 or 4 shots of spray you will need to remove the float bowl and clean it and the main jet with the carb cleaner.
Protect your eyes and bare skin while using the carburetor cleaner, it will injure you. Do not spray it on any rubber gaskets or seals, it will swell and ruin them.
Sorry for the "book" I wrote but I am trying to explore as many possibilities as I can to get you up and snow blowing!

Testimonial: "Cured the problem just like you said. Thanks"
Sounds like it is the valve seats. However normally it will stop smoking after is runs for a while if that is the problem. Does it run good? Because if it isn't the valve seats then it is the rings. Or a big scratch in the cylinder wall. Then most of the time it will loose compression. If it isn't smoking real bad then you can get an additive to put with your oil that will make it stop, maybe? It is about ten dollars and you can get is at most autoparts stores. It will just take a couple ounces of it. Follow the directions for how many qts of oil you have. After you change the oil in the motor take a magnet and run it through the oil and see if there is pieces of the rings in it.

SOURCE: Hello' My issues is as follow: my MTD PRO Hydrostatic 18.0 HP 1/C OHV, I have gas runing inside of the oil compartment; as well as, inside were the Spark plugs should be? do know what is the pro
Th carb needle is leaking, with an internally vented carb there is the possibility for the fuel to flow through the open inlet valve if the carb needle is not shutting the fuel off, if this happens after the machine has been left, just fit an inline fuel tap in the fuel hose, however the needle valve will have to be changed at some point.

Testimonial: "Mike was correct... The fix was simply 'adjust the valves'. This apparently affects that 'compression release valve' that mike spoke of. We measured the exhaust clearance-- it was .063" We reset it to the recommended .007" (what a difference) The intake valve clearance measured .025" We reset it to the recommended .005" I don't understand the design mechanics of the 'compression realse valve'... or where its located... but it definatly works. Anyone know where to find the exploded view of this Briggs?"
SOURCE: I have a 1993 Kohler CH18 engine. I was mowing the lawn and the engine started losing power. I was able to make a couple more rounds and finish mowing. I then noticed that the low oil light was on.
a plugged passage will block of the flow
